TSP 5.3L vs. LS6

[rapter34]

Since I have just replaced my 10 bolt with a 9" I finnaly feel like I got the last weak link out of my car. I think I am ready to get a head cam package done. I have been very interested in eaither the Stage 2.5 5.3L or LS6 from TSP. Is the LS6 worth the extra $300 and also would a torquer V.2 be better with a 114 or a 112LSA?

Thanks

anyone?

what are your goals for the car???

[Mr. Luos]

Do you have to pass emissions?

Compression maximum?

i just used the 5.3 stage 2.5 heads/ Long tube headers/ MS3 cam 237/242 .603/609 on a 112.. Pulls like a beotch... No dyno numbers.. still tuning on it.. Depends on where you are lookin for the HP..

[rapter34]

don't have to pass emissions and don't really have a compression maximum right now. just wonderi HP gains and trying to find out what is important in selectong heads. questions like what are the conciquencies for going with a higher CR? I want the car to be well mannered enough that I can just drive around town and also have enough get up and go to get me in the 11's. Right now my drivtrain is pretty good with spec 3 clutch, steel flywheel, and 9" in the rear. Sorry if im confusing im just trying to find the right course of action.

[Mr. Luos]

The 5.3 heads will bump compression a little bit. Not sure how much off the top of my head....bumps to something like 10.6:1.


I would personally go with the LS6 heads and a 228R from TSP.

[rapter34]

any reason why you would go with that selection?

[Mr. Luos]

Very streetable and a very nice powerband.

[rapter34]

Is the torquer 2 not a very streetable cam?

[Mr. Luos]

It isn't bad. But everyone has their own opinion of what is streetable.
I am not a fan of the huge cams without being a drag car and set-up for it.

I missed it...car an auto or manual?

[rapter34]

its an M6 and why would you go LS6 over 5.3L? Also is there any differance in the LSA's besides how much chop there is in the idle?

[Mr. Luos]

Flow in the lower lift numbers.

[rapter34]

I don't think I edited my last question fast enough what is the diiferance in LSA besides the amount of chop at idle?

Lower LSA lowers the powerband in the RPM range. But comes on stronger.

Stolen from Tech...

- Bigger duration cams will have more overlap then a smaller duration cam even if both are on the same LSA.

- The key to making overlap work is maximizing the power in the rpm band where you want it.

- Long overlap periods work best for high-rpm power. For the street, a long overlap period combined with long-duration profiles combine to kill low-speed torque

- Reducing overlap on a long-duration cam will often increase midrange torque at the expense of peak power, but if the average torque improves, that’s probably a change worth making.

- Many enthusiasts purchase a camshaft strictly on the basis of how it sounds. A cam with generous overlap creates that distinctive choppy idle that just sounds cool.

Thanks Mr. Luos im getting some really helpful stuff here. Is there anyone else on here who has the combinations of these differant setup ie. 228R, LS6, 5.3, or torquer V.2 to give me a feel how they are in life?

I have a 228R on a 114 with PRC 5.3L heads. Love it. No dyno numbers but it's a nice car to drive on the street. Good manners with plenty of balls and if I recall correctly the advertised compression with the 5.3's is 10.75:1
